The copyright information from the title screen on a black background.

White text for the title screen that says "TGS ver.". It was probably used during the Tokyo Game Show.

An unused background that can be seen in a trailer that was included in Sonic Mega Collection. In the final game, it is seen in the options menu.

Unused Acts

Each Zone has four Acts. The first two Acts are the regular Acts, while Act 3 is the Zone's "Boss Attack" Act - Act 4 goes unused for all Zones. All instances of Act 4 use the same foreground (a single platform with a roof of spikes, based on the Super Eggrobo Z's arena at the end of XX), as well as the background from the corresponding Zones.

Multiplayer Team Play

To do: Add codes to access this.

Sonic Advance had the option to enable team play when playing in multiplayer modes. Such a feature was dropped for Sonic Advance 2, however coding for team play remains in the game. It can be enabled via hacking the game to call the team play setup screen after multiplayer connection has been initialised.

Team play is largely complete, and teammates can interact with each other. Code for team-specific character actions is left over from Sonic Advance, though is partially functional:

• Sonic's team action (boosting teammates with his Spin Dash) works as intended.
• Tails' and Knuckles' team actions (carrying teammates while flying/gliding) will cause their teammate to be stuck in the air with no way to control them.
• Amy's team action (catapulting teammates upward with her Piko Piko Hammer) doesn't function at all.
• Cream has no team action coded for her.

Graphical glitches will also occur on the results screen for players from the winning team, but not for losing players.

Debug Save

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: Verify that this is intentional behaviour and not just a bug.

Not having an SRAM chip on the cartridge will unlock everything in the game. This is also the case for the other Sonic Advance games.

Regional Differences

A grammatical error is present in the title card of True Area 53 in the Japanese version. This was corrected is the US version but is oddly still present in the European version.
